**u**is a vector-valued function. Is it true that

(∇×

**u**)

**⋅**( (

**u⋅**∇)

**u**) = (

**u⋅**∇)(∇×

**u**)

**⋅u**

?

Please note the lack of a dot product on the first two terms of the RHS and the parenthesis around the second term of the LHS. I'm trying to understand whether these differential operators are associative.
